Android translate animation is different the second time I created a very simple translate animation, when the button is pressed for the first time, an image view will move to the left, and the second it will move to the right. The distance is exactly the same. But the second time the image moves more and actually doesn't come back to its original position. To be more accurate, the second time the image goes twice the distance. Why? private var direction = 1 fun move() { val animatorX = ObjectAnimator.ofFloat(draggableImage1, "translationX",...

Prevent translation animation from keeping the original position of view Using the translation animation with a value of say 50f on the x axis will move the object 50 pixels to the right: val animatorX = ObjectAnimator.ofFloat(draggableImage1, "translationX", 50f) But after that translation, the animation still "remembers" the original position of the object, so calling the exact same method again won't move the object at all, because it's already set 50 pixels to the right. Is this way to prevent this behavior? Meaning, after the animation was complete, the...
